ok I'm officially confused. I have drum struts/hubs and the s13 setup. IF I understand correctly, I need not only the adaptor but also a spacer block? Has anyone got a template I can get a hold of?

I tried fitting my s13 rotor onto the drum hub today and no go, the centre hole needs to be bored out by nearly 10mm. Is this what everyone else has found??

I recently built up another set of the S13 [CA 250mm rotor] conversion on B110 drum hubs and KB110 struts. In order to get the caliper to rotor allignment correct, I sacraficed the original drum and machined it on a lathe and turned it into a spacer [5.05mm].

I did not have to modify the drum hub at all.
I did not have to modify the rotor either.

how do i contact this "kev rowley"?

cheers

god i love this site.

i have now got my rotors and calipers, and drum struts ready to get started on this, can anyone point me in the right direction for someone who sells the brackets?
cheers

Does anyone have a drawing (With measurements) of the s13 caliper to disc brake stub axle adapter? It seems that there is a flaw in the deisgn of the ones I've been using.
